Delete an array element based on value from nested array - php

I have try to remove whole parent array using PHP unset(key) function based on value from a nested array in it.
Nested array looks like
Array (
[0] => Array (
[ID] => 9909
[SHIPPING_AMOUNT] => 5
[TOTAL_TAX] => 0
[GRAND_AMOUNT] => 49.97
[ITEMS_AMOUNT] => 44.97
[ITEMS] => Array (
[0] => Array (
[CODE] => TEST
[QTY] => 1
[UNIT_PRICE] => 14.99 )
[1] => Array (
[CODE] => NNKIT
[QTY] => 1
[UNIT_PRICE] => 9.99 )
[2] => Array (
[CODE] => MAINKIT
[QTY] => 1
[UNIT_PRICE] => 19.99 )
)
)
[1] => Array (
[ID] => 9910
[SHIPPING_AMOUNT] => 5
[TOTAL_TAX] => 0
[GRAND_AMOUNT] => 74.96
[ITEMS_AMOUNT] => 69.96
[ITEMS] => Array (
[0] => Array (
[CODE] => NNKIT
[QTY] => 1
[UNIT_PRICE] => 9.99 )
[1] => Array (
[CODE] => MAINKIT
[QTY] => 3
[UNIT_PRICE] => 19.99 )
)
)
[2] => Array (
[ID] => 9911
[SHIPPING_AMOUNT] => 5
[TOTAL_TAX] => 0
[GRAND_AMOUNT] => 44.98
[ITEMS_AMOUNT] => 39.98
[ITEMS] => Array (
[0] => Array (
[CODE] => MAINKIT
[QTY] => 2
[UNIT_PRICE] => 19.99 )
)
)
[3] => Array (
[ID] => 9912
[SHIPPING_AMOUNT] => 5
[TOTAL_TAX] => 0
[GRAND_AMOUNT] => 29.98
[ITEMS_AMOUNT] => 24.98
[ITEMS] => Array (
[0] => Array (
[CODE] => TEST
[QTY] => 1
[UNIT_PRICE] => 14.99 )
[1] => Array (
[CODE] => NEWTEST
[QTY] => 1
[UNIT_PRICE] => 9.99 )
)
)
and value which I check for is CODE = MAINKIT. If not exists in a nested array then main array should be removed (in this case parent array[3]) but somehow returned key is from nested array not a parent one.
PHP code:
foreach($array as $key => $value){
if(is_array($value) && $value['CODE'] != 'MAINKIT')
unset($key);
}

The CODE elements are inside the $value['ITEMS'] array, not directly in $value.
To tell whether MAINKIT isn't in any of the items, you have to loop through all the items, testing whether any of them matches. If none do, then delete the array element.
Try:
foreach($array as $key => $value){
if (is_array($value) && is_array($value['ITEMS']))
$found_mainkit = false;
foreach ($value['ITEMS'] as $item) {
if($item['CODE'] == 'MAINKIT') {
$found_mainkit = true;
break;
}
}
if (!$found_mainkit) {
unset($array[$key]);
}
}
}

Rearrange items in multidimensional array

I have a multidimensional array, I want to take the key 'data' from each array item and form another array, like first array 'data' element has 3 items, second has 1 item, 3rd and 4th are empty, and 5th has one item, I want to make a separate array like $temp_array['first_item_from_first_array,..., first_item_from_fifth_array, 'second_item_from_second_array,....,second_item_From_fifth_array]
input array is,
Array

You need to do it like below:-
$data_array= array_column($array,'data');
$count = 0;
foreach($data_array as $data){
$real_count = count($data);
if($real_count > $count){
$count = $real_count;
}
}
echo $count;
$final_array = [];
foreach($data_array as $data_arr){
for($i=0;$i< $count; $i++){
$final_array[$i][] = (count($data_arr[$i])>0)? $data_arr[$i]: array();
}
}
echo "<pre/>";print_r($final_array);
Output:-https://eval.in/925383
Reference:- PHP: array_column - Manual
You can use array_column() function
Example :-
<?php
$array = [
[
"meal_type" => "bf",
"data" => [
"name" => "test",
"email" => "test#ymail.com"
]
],
[
"meal_type" => "bf",
"data" => []
]
];
echo "<pre>";
print_r(array_column($array, "data"));
?>
You can do this using foreach and array_push.
$data_item_array = [];
foreach ($array as $item) {
$data = $item['data'];
foreach ($data as $t) {
array_push($data_item_array, $t);
}
}
print_r($data_item_array);
Output will be :
Array
(
[0] => Array
(
[id] => 109
[label] => testfrom
[quantity] => 12
[unit] => g
)
[1] => Array
(
[id] => 118
[label] => test
[quantity] => 200
[unit] => oz
)
[2] => Array
(
[id] => 121
[label] => test
[quantity] => 10
[unit] => g
)
[3] => Array
(
[id] => 120
[label] => testfrom
[quantity] => 12
[unit] => g
)
[4] => Array
(
[id] => 119
[label] => test
[quantity] => 200
[unit] => oz
)
)

Iterating recursively through an array

Update: I have a solution - please see below for details.
I have an array where the keys are levels (in a navigation tree for example) - something like
Array
(
[0] => Array
(
[100] => Array
(
[name] => foo100
[slug] => foo100
[id] => 100
[parent] => 0
[level] => 0
)
[101] => Array
(
[name] => foo101
[slug] => foo101
[id] => 101
[parent] => 0
[level] => 0
)
)
[1] => Array
(
[200] => Array
(
[name] => foo200
[slug] => foo200
[id] => 200
[parent] => 100
[level] => 1
)
[201] => Array
(
[name] => foo201
[slug] => foo201
[id] => 201
[parent] => 101
[level] => 1
)
)
[2] => Array
(
[300] => Array
(
[name] => foo300
[slug] => foo300
[id] => 300
[parent] => 200
[level] => 2
)
[301] => Array
(
[name] => foo301
[slug] => foo301
[id] => 301
[parent] => 201
[level] => 2
)
)
[3] => Array
(
[400] => Array
(
[name] => foo400
[slug] => foo400
[id] => 400
[parent] => 300
[level] => 3
)
)
[4] => Array
(
[500] => Array
(
[name] => foo500
[slug] => foo500
[id] => 500
[parent] => 400
[level] => 4
)
)
)
I need to create an array from this which iterates from the top most level and creates an array with the key being the slug of that level - to produce the following:
Array
(
[foo500] => Array
(
[4] => Array
(
[name] => foo500
)
[3] => Array
(
[name] => foo400
)
[2] => Array
(
[name] => foo300
)
[1] => Array
(
[name] => foo200
)
[0] => Array
(
[name] => foo100
)
)
[foo400] => Array
(
[3] => Array
(
[name] => foo400
)
[2] => Array
(
[name] => foo300
)
[1] => Array
(
[name] => foo200
)
[0] => Array
(
[name] => foo100
)
)
[foo300] => Array
(
[2] => Array
(
[name] => foo300
)
[1] => Array
(
[name] => foo200
)
[0] => Array
(
[name] => foo100
)
)
[foo301] => Array
(
[2] => Array
(
[name] => foo301
)
[1] => Array
(
[name] => foo201
)
[0] => Array
(
[name] => foo101
)
)
[foo200] => Array
(
[1] => Array
(
[name] => foo200
)
[0] => Array
(
[name] => foo100
)
)
[foo201] => Array
(
[1] => Array
(
[name] => foo201
)
[0] => Array
(
[name] => foo101
)
)
[foo100] => Array
(
[0] => Array
(
[name] => foo100
)
)
[foo101] => Array
(
[0] => Array
(
[name] => foo101
)
)
)
I hope this explains the issue - struggling to get this right! Any help much appreciated!
Update - solution.
For this I removed the first level of keys to leave
Array
(
[107] => Array
(
[id] => 107
[name] => About Us
[indexID] => about
[level] => 0
[parent] => 0
)
[109] => Array
(
[id] => 109
[name] => Home
[indexID] => index
[level] => 0
[parent] => 0
)
}
etc etc
Assuming $data is the above array I went with:
foreach ($data as $k => $v) {
if ($v['parent'] == 0) {
$bc[$v['indexID']][0]['name'] = $v['name'];
$bc[$v['indexID']][0]['indexID'] = $v['indexID'];
}
else {
$nextParent = $v['parent'];
$currentIndexID = $v['indexID'];
$currentName = $v['name'];
$bc[$v['indexID']][0]['name'] = $currentName;
$bc[$v['indexID']][0]['indexID'] = $currentIndexID;
for($i=1;$i<=$level;$i++) {
foreach ($data as $a => $b) {
if ($a == $nextParent) {
$nextParent = $b['parent'];
$bc[$v['indexID']][$i]['name'] = $b['name'];
$bc[$v['indexID']][$i]['indexID'] = $b['indexID'];
}
}
}
}
}

How to reformat an array using php?

I have the following array:
Array
(
[0] => Array
(
[Import] => Array
(
[id] => 1
[category_id] => 2
[product_id] => 2
[amount] => 50

)
)
[1] => Array

(
[total_sell] => 10
[no_contact] => 1
[confirmed] => 2
[canceled] => 0
)
)
[2] => Array
(
[Import] => Array
(
[id] => 3
[category_id] => 2
[product_id] => 1
[amount] => 15
[cost] => 2000
[comment] =>
[created] => 2015-06-23 19:20:15
)
[0] => Array
(
[total_sell] => 10
[no_contact] => 0
[confirmed] => 0
[canceled] => 0
)
)
)
I want to remove duplicate value of same product_id inside [Import][product_id] but want sum [Import][amount]. My expected array is:
Array
(
[0] => Array
(
[Import] => Array
(
[id] => 1
[category_id] => 2
[product_id] => 2
[amount] => 65
[cost] => 8320
[comment] => transportation and others cost: 100
[created] => 2015-06-23 19:21:10
)
[0] => Array
(
[total_sell] => 10
[no_contact] => 1
[confirmed] => 2
[canceled] => 0
)
)
[1] => Array
(
[Import] => Array
(
[id] => 3
[category_id] => 2
[product_id] => 1
[amount] => 15
[cost] => 2000
[comment] =>
[created] => 2015-06-23 19:20:15
)
[0] => Array
(
[total_sell] => 10
[no_contact] => 0
[confirmed] => 0
[canceled] => 0
)
)
)
It will be really a gift if anyone give a function to solve this issue.
$filteredArray = [];
foreach ($array as $productData) {
if (isset($filteredArray[$productData['Import']['product_id']])) {
$filteredArray[$productData['Import']['product_id']]['Import']['amount'] += $productData['Import']['amount'];
}
else {
$filteredArray[$productData['Import']['product_id']] = $productData;
}
}
print_r($filteredArray);
Ah.. forgot to mention - $array is Your base array.
/**
* Removes duplicate summing amount from products array
*
* #param array $array
* #return array
*/
function removeDuplicates($array)
{
$idsCount = array();
foreach ($array as $key => $value) {
$idsCount[$value['Import']['product_id']]['count'] += 1;
$idsCount[$value['Import']['product_id']]['sum'] += $value['Import']['amount'];
if ($idsCount[$value['Import']['product_id']]['count'] > 1) {
unset($array[$key]);
$array[$idsCount[$value['Import']['product_id']]['key']]['Import']['amount'] = $idsCount[$value['Import']['product_id']]['sum'];
} else {
$idsCount[$value['Import']['product_id']]['key'] = $key;
}
}
return $array;
}
i know it looks crazy but is formatted on your specific array.

Would you write a function to filter this type of array and produce expected result. I have been googling for 2 days but no luck.
This is a handy one liner that should do the trick:
$unique= array_map("unserialize", array_unique(array_map("serialize", $original)));
If the underlying arrays are not identical, that won't work, in which case I think you could do:
$unique = array_intersect_key($original ,
array_unique(
array_map(function($item) {
return $item['Import']['product_id'];
}, $original)
)
);
Tested: http://sandbox.onlinephpfunctions.com/code/8aee5cbd614e0ddd1a03dfaa7e98c72fbbe7d68d
Here is a quick stable sort and reduce which runs in linearithmic time. First-encountered product Id's are kept, and entries with duplicate product Id's are ignored.
// Stable sort
sort($in);
// Reduce
$out = array_reduce($in, function(&$acc, &$item){
if($item['Import']['product_id'] !== #$acc[sizeof($acc)-1]['Import']['product_id']) {
$acc[] = $item;
}
return $acc;
}, []);
Demo: http://ideone.com/BP0eUJ
Update: Here is an even better linear-time algorithm that does the same as above using a fast "hash table" lookup. Again, the first-encountered product Id is kept and subsequent ones of the same Id are ignored.
$out = [];
$hashTable = [];
foreach($in as $item) {
$pid = $item['Import']['product_id'];
if(!isset($hashTable[$pid])) {
$out[] = $item;
$hashTable[$pid] = true;
}
}

array difference

I have this array lets call it array 1
Array
(
[0] => Array
(
[Machine] => Array
(
[id] => 7
[name] => XYZ
[priority] => 1
)
[Software] => Array
(
[id] => 472
)
)
[1] => Array
(
[Machine] => Array
(
[id] => 6
[name] => ABC
[priority] => 0
)
[Software] => Array
(
[id] => 470
)
)
[2] => Array
(
[Machine] => Array
(
[id] => 1
[name] => IEU
[priority] => 3
)
[Software] => Array
(
[id] => 471
)
)
)
Then I have another array lets call it array 2
Array
(
[0] => 7
[1] => 5
[2] => 4
[3] => 3
[4] => 6
)
If array 2 doesnt have [Machine][id] then I want it to be removed from array 1. Like in above example 1 will removed
[2] => Array
(
[Machine] => Array
(
[id] => 1
[name] => IEU
[priority] => 3
)
[Software] => Array
(
[id] => 471
)
)
any idea on how to achieve that. Thanks
Perhaps..
foreach ($array1 AS $key => $array) {
if (!in_array($array['Machine']['id'], $array2))
unset($array1[$key]);
}
try something like :
$new_array = array();
foreach ($array1 as $platform)
{
if (in_array($platform["Machine"]["id"], $array2))
{
$new_array[] = $platform;
}
}
return $new_array;
